I have initiated a new project that has encountered some challenges along the way. Recently, I purchased a PLC device, specifically a FX1N-20MR, along with the GX Developer version 8 software. After conducting extensive research on YouTube and Google, I successfully connected to the device and programmed a basic ladder logic. However, I encountered an issue when attempting to test the logic by forcing bits on in "Monitor (write mode)." Unlike the videos I have seen where bits light up blue and timers start counting, my software does not display any visual cues when forcing bits on. The only indication of communication with the device is the mini window updating when transitioning between RUN and STOP modes. Can anyone provide insight on why I am not seeing the expected highlights for function testing purposes?
Do you consider 'bits' as inputs like X0, etc.? Real inputs cannot be imposed on the model, but bits can be used instead.
If the bits in your program are altered, they will not be affected by manual manipulation. Experiment with a different M or D register that is not currently in use within your program for potential changes.
Hey there, it seems like you've made some good progress already! Now, onto the issue you're facing. Although there could be several reasons why this is happening, one possibility is that you might be experiencing a version compatibility issue between your PLC device and the GX Developer software. Keep in mind that different versions of the software can have varied user interfaces and features. If possible, make sure both your PLC model and software version are compatible. Also, verifying whether there are any updates available could be helpful. If the problem persists, trying another model or version of the software might be worth it. We are all here to help and learn from each other, so don't hesitate to ask if you come across any more challenges.
Hello, the issue you're experiencing might be related to the software rather than the PLC device itself. It seems like you don't get visual feedback when forcing bits on, which can definitely make your work harder to manage. If you've recently downloaded GX Developer, try uninstalling and reinstalling it, or updating it to the latest version if applicable. Sometimes, minor bugs or compatibility issues can be the culprit. If this doesn't solve it, you might want to reach out to Mitsubishi's support team directly. They've been really helpful in my experience with troubleshooting specific PLC issues.
It sounds like you're making great progress with your FX1N-20MR, but I get how frustrating it can be when things don’t work as expected. One possibility could be related to the configuration settings in GX Developer; sometimes, the visual feedback features need to be explicitly enabled in the project settings. Another thing to check is if your device is compatible with the specific version of GX Developer you're using since older devices sometimes have quirks with newer software. Have you also verified that your PLC firmware is up to date? It might seem tedious, but going through the setup step-by-step again could reveal something amiss. Good luck, and hope you get it sorted soon!
It sounds like you're making great progress with your PLC project! The issue you're encountering with the bits not lighting up could be related to a couple of factors. First, double-check that you're in the right mode for monitoring; sometimes the software has specific settings for visual feedback. Additionally, make sure that the connection settings for the FX1N are configured correctly and that you're not in a simulation mode, as that might prevent the visual indicators from working as expected. If everything seems correct, it might be worth looking for software updates or even reaching out to forums specific to GX Developer for more tailored advice. Good luck with your project!

Answer: Answer: The lack of visual cues such as bits lighting up blue and timers counting in GX Developer could be due to various reasons, including incorrect software settings, communication issues with the PLC device, or compatibility issues between the software version and the PLC model.
Answer: Answer: To troubleshoot connection issues, ensure that the correct communication settings are configured in GX Developer, verify the cable connections between the PLC device and the computer, check the device address settings, and confirm that the appropriate drivers are installed on the computer.
Answer: Answer: To address the absence of visual cues during function testing, consider checking the software configuration settings related to monitoring and forcing bits, verifying the program logic for any errors or inconsistencies, updating the software to the latest version compatible with your PLC model, and consulting the GX Developer user manual for troubleshooting guidance.
